Abstract
A hybrid vehicle 20 of the invention is equipped with a power distribution integration mechanism 40 and a transmission 60. The power distribution integration mechanism 40 includes a carrier 45 connecting with a motor MG2, a sun gear 41 connecting with a motor MG1, and a ring gear 42 connecting with an engine 22. The transmission 60 includes a first change speed planetary gear mechanism PG1, a second change speed planetary gear mechanism PG2, a brake clutch BC1 configured to fix a ring gear 62 of the first change speed planetary gear mechanism PG1 in a non-rotatable manner and release the ring gear 62 in a rotatable manner and to couple the ring gear 62 with a common carrier 64 shared by the first change speed planetary gear mechanism PG1 and the second change speed planetary gear mechanism PG2, and a second brake clutch BC2 configured to fix a ring gear 66 of the second change speed planetary gear mechanism PG2 in a non-rotatable manner and release the ring gear 66 in a rotatable manner and to couple the ring gear 66 with the common carrier 64.
